tgMochiKit

I recently came across tgMochiKit, a valuable TurboGears widget that packages the famous MochiKit JavaScript library. Authored by Bob Ippolito, this powerful tool offers two primary use cases: it can be utilized as a standalone widget or as a resource for other widgets.

If you choose to use tgMochiKit as a standalone widget, the process is simple. TurboGears can integrate the widget on every page, allowing other JavaScript code on the page to utilize the functions of the MochiKit library. To enable this, developers can simply set the following in their application's main configuration: tg.include_widgets = ['turbogears.mochikit']. It's important to note that the mochikit widget object lives in the turbogears module, as TurboGears initializes the widgets package and selects the appropriate MochiKit version based on the application's configuration.

Alternatively, if a JavaScript-enabled widget relies on the MochiKit library, declaring the tgMochiKit widget as a resource by adding it to its javascript class attribute is the way to go. For instance, a small sample widget that utilizes the MochiKit Logging module could be represented as follows:

from turbogears import widgets, mochikit
class LoggingPanelLink(widget.Widget):
template = """open logging pane"""
javascript = [mochikit].

tgMochiKit has been a valuable addition to my toolkit, aiding me in maximizing my use of the MochiKit library in JavaScript development.
